Demonstration of Floppy Drive, CD Drive and Hard Disk.

Floppy Disc Drive

• A floppy disc, sometimes referred to as a floppy diskette, floppy, or floppy disc, is a type of storage medium that can read data storage information and is used to store electronic data, such as a computer file. 
• It was one of the first types of hardware storage that could read and write to a portable device, developed by IBM in 1967, but it was also quite expensive.

• When they were first created, they were 8 inches in diameter and users couldn't write data to them like CD-ROM. 
• The maximum amount of data that could be stored on this disc was just 80 KB, although later models could hold up to 800 KB. 
• Devices like USB and network file transfer have taken the place of floppy discs, but these discs are now out of date.
• A floppy disc was available in three sizes, 8 inches, 5.5 inches, and 3.5 inches, as technology developed. The latest floppy device can store more data and makes use of more advanced technology than earlier ones.

Hard Disk

• Previously known as a fixed disc, a hard disc is now also referred to as an HDD (hard disc drive) or hard drive. 
• It is a kind of non-volatile storage device that uses quickly spinning platters with magnetic surfaces to store data that has been digitally recorded. Hard drives and hard discs are two other prevalent names for hard discs.
• The storage medium itself is referred to as a "hard disc" (sometimes spelled "platter" or "disc"), but a "drive" is a complete apparatus made up of numerous platters, a read/write head assembly, driver electronics, and a motor. The original purpose for creating computers was so they could use hard discs.
• Hard discs are used in personal digital assistants (PDAs), digital cameras, digital video recorders, digital audio players, and computers in the twenty-first century.
• The first mobile phones with hard discs were released in 2005 by the Samsung Group and Nokia. Nokia was the manufacturer of these phones.
• Large data sets needed to be accessed efficiently, which prompted the creation of storage configurations like RAID, hardware like network attached storage (NAS) devices, and systems like storage area networks (SANs). 
• These developments were made possible by the requirement for reliable, large-scale storage that was not reliant on a single device.
